RSNeely Posted December 14, 2014 Report Share Posted December 14, 2014 First time posting in the plastics forum. I am starting to get my gear together for pouring plastics. Im curious, can you hand pour into a injection style mold? I ask because ive seen a few hand poured craws (with veins, different color arms), and I can only find a injection style mold. Sorry, maybe this is a dumb question. Quote Link to comment Share on other sites More sharing options...
DaveMc1 Posted December 14, 2014 Report Share Posted December 14, 2014 Look at LureCraft for 1pc hand pour molds. They should have a few aluminum molds from DelMart and they will have a HUGE selection of silicone 1pc molds. The vast majority of injection molds do require an injector to push the plastic into them. I will tell you now that hand pouring into 1pc molds is an art and take a lot of patients and practise to develop the techniques you want to master, Quote Link to comment Share on other sites More sharing options...
RSNeely Posted December 14, 2014 Author Report Share Posted December 14, 2014 Thank you! I guess to reword my question, can I use an injection mold to hand pour? Meaning, opening it up to pour into. Quote Link to comment Share on other sites More sharing options...
DaBehr Posted December 14, 2014 Report Share Posted December 14, 2014 Yes....I hand pour the belly or lower part of many injection baits. Then I close the mold and shoot the top. No...you can't hand pour the entire mold if it's a two piece injection mold. Yes...you hand pour (straight from the cup) for "top pour" two piece molds. A good example is a stick bait mold.

gone2long Posted December 14, 2014 Report Share Posted December 14, 2014 Mold configuration and size of appendages and the like will tell you if it's possible but not many can be hand poured and is not worth the effort except for those occasions when you are doing laminates but you would still need to inject the second half. When you see different colored claws for example that was injected and the claws cut from the body and left in the mold then the body color is injected.

RSNeely Posted December 15, 2014 Author Report Share Posted December 15, 2014 So then i can't put a vein in the middle of my baits using injection molds correct? Quote Link to comment Share on other sites More sharing options...
MonteSS Posted December 15, 2014 Report Share Posted December 15, 2014 Hand pour 1/2 the mold with a transparent color. Handpour a vein in darker/brighter color. Close mold and inject Quote Link to comment Share on other sites More sharing options...
Bassinfool Posted December 15, 2014 Report Share Posted December 15, 2014 You can certainly get a vein using injectors. I've hand poured the bottom and top halves of my molds and then injected my vein color which works well. I know a few guys pour half their mold and let it cool and then put a drop of colorant on top of the poured plastic near the gate, close the mold and inject the top color.

gone2long Posted December 16, 2014 Report Share Posted December 16, 2014 As stated that's doable you just can't hand pour any ole injection mold the plastic is not thin enough to make it's way down to the smaller parts of many baits, you can do allot of things as stated including laminates veins even 3 and 4 color baits with some hand pour practice combined with injection and a good eye. 2 Quote Link to comment Share on other sites More sharing options...
